Why stealth through small radar dot, when we could have stealth through making the dot so large it's impossible to know where it's coming from? Are they stupid?

A community for your defence shitposting needs
Rules
1. Be nice
Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.
2. Explain incorrect defense articles and takes
If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.
3. Content must be relevant
Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.
4. No racism / hatespeech
No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.
5. No politics
We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.
6. No seriousposting
We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.
7. No classified material
Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.
8. Source artwork
If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.
9. No low-effort posts
No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.
10. Don't get us banned
No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.
11. No misinformation
NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.

Radar works like this; imagine you're playing hide and seek in the woods after dark. You have a flashlight and you think it's a good idea to shine it around looking for your buddies, and if you see them with the flashlight that's the radar dot. Making the dot big is like having all your buddies who are supposed to be hiding also having REALLY BIG flashlights, so bright that you can't see what you're looking at very well.
In warfare the hide and seek game also includes a gun, and even a really bright light still more or less tells you exactly where it's coming from allowing you to shoot at the light until it goes out. Not great for the survivability of the hiders!
The smart hider might set up their jamming light somewhere else so the seeker shoots at nothing, however the lights are still very expensive and they make cheap rockets designed to home in directly on radar and blow it up. The least expensive way overall for the hider to avoid the seeker is for the hider to wear all black clothing and be small.
Here's the idea: A plane that carries a radar emitter so strong that it blows out the receivers on enemy radar towers/SAM sites/ARAD missiles. It's tethered to another plane that carries a nuclear reactor to power it. And another one carrying a cooling system.
(Note: I'm not talking about a radar jammer. Jamming is a chickenshit solution that stops being useful when the jammer stops working. I'm talking about physically destroying the receivers by overloading them.)
What you're talking about is essentially an EMP. They don't generally emit continuously. Instead you just set off a single strong pulse which induces such high currents in receiving antennas that they melt or otherwise damage connected circuitry.
At these levels of power, any amount of conductive material tends to start acting as an antenna. If you set up a continuous transmitter you're going to have trouble not damaging your own delivery and power mechanisms.
The most common way to generate one is to set off a nuclear bomb that has been finetuned to release most of its energy as electromagnetic radiation.
